I'm struggling getting it to work reliably at the moment. There's just been new firmware released for the BC95 but I've yet to check to see if the problems I've encountered have been fixed. Then there's the challenge of updating the firmware - I've soldered some wires to bridge the BC95 serial to the usb->serial board so I can do this.
The first trick to getting the BC95 working is to swap the gprs tx and rx pins (12 & 20) in rak8211.js. It's easy enough just to hand edit the min.js file as it is the first line.
